Justin Bamberg tweeted a photo of Kim, Kanye West, and Cameron Sterling, Alton Sterling’s eldest son. “Shoutout to @kanyewest & @KimKardashian for showing 16th bday love last night to my client #CameronSterling, eldest son of #AltonSterling,” he wrote. Alton Sterling was killed by police over the summer, sparking national protests and prompting Kim to write an open letter about #BlackLivesMatter.

“I want my children to grow up knowing that their lives matter,” Kim wrote at the time. “I do not ever want to have to teach my son to be scared of the police, or tell him that he has to watch his back because the people we are told to trust — the people who ‘protect and serve’ — may not be protecting and serving him because of the color of his skin.”
